Abstract
A numerical simulation study of the Mori geothermal field was carried out to analyze and predict the behavior of the reservoir, production wells and re-injection wells. This study consisted of three-dimensional natural state modeling, history matching and future prediction. The numerical model provided satisfactory matches of temperature and pressure profiles in the natural state and of wells’ temperature and pressure history during exploitation. Therefore the numerical model constructed in these simulations was thought to be able to reproduce the actual field conditions.
By using this numerical model, the total steam flow rate trends were predicted for several different scenarios over the next 10 years. The results indicate that the reservoir will be able to sustain stable total steam production by drilling new production wells and new re-injection wells. With the addition of these new re-injection wells, the flow rate of the existing re-injection well that have adverse effects on some of the existing production wells can be decreased.
